Medical education would it intended only infused science? Some may balk side "childish" this book ... How to read an ECG is actually not rocket science, yet when I see the average level of the external medicine (sometimes even the internal or senior "not Cardiologist") in the interpretation of ECG bedside, I say that knowing the Dubin method is already for them a more solid basis than the daily - which method is already, I think, in its 6th edition in 1972 in the United States.
A head of clinical resuscitation has never regretted potash Dubin in his "younger years", and that always puts at the disposal of its students (and has no complaints also on the excellent book by Pierre Taboulet).
